ZÖLLNER ZET-Horn – Electrically Operated Horn Ship class I

A piston in a cylinder is propelled by an AC 3phase motor which then makes the air in the sound horn vibrate and produce the sound.
Since the low signal frequency of 70 Hz is fairly pleasant, the ZET-Horn 70 AC is preferred on luxury passenger ships.
Other versions of all types with a special heating system for arctic class vessels as well as special editions for luxury yachts
